Dr. Judd Walson, an Associate Professor at the University of Washington, completed his Internal Medicine and Pediatrics training at Duke University, and his fellowship in Infectious Disease at the University of Washington. He also holds a Masters in Public Health from Tufts University. Dr. Walson has extensive experience in designing and implementing clinical trials in resource-limited settings and has lead complex projects in Kenya, Ethiopia, Bangladesh, Thailand and Nepal. His research focuses on the intersection between infection (particularly parasitic and bacterial enteric infection), and growth and development. Dr. Walson is currently the Principal Investigator of a large NIH randomized trial in Kenya evaluating the use of azithromycin to reduce post discharge mortality and is the Kenya site Principal Investigator for a seven country trial of interventions to reduce diarrhea associated mortality in young children. In addition, he is also the Principal Investigator of DeWorm3, a large multi-country trial based at the Natural History Museum in London which is designed to evaluate the feasibility of interrupting the transmission of soil-transmitted helminths, or intestinal worms in Benin, India and Malawi. Dr. Walson also directs the Global Health Strategic Analysis and Research Training Program (START), an innovative collaboration between the Bill & Melinda Gates Foundation and the University of Washington. This program provides analytic support to organizations working in both global and domestic public health. Dr. Walson will capitalize on his broad research and management experience as co-Principal Investigator of The CHAIN Network with Professor Jay Berkley.
